PM103x Optical Power Meter Interfaces Chapter 4 Operating Instructions
4.2.2.1 PM103
PM103 Special Features
The PM103 version of PM103x features a number of additional options, due to the DA-15 output
connector.
The PM103 is per default configured to RS232 configuration (+/- 5 V voltage level). This can be changed
to a UART configuration (0/5 V voltage level) such that the PM103 can be accessed by external micro-
controllers for instrument control and data export. The PM103 can also be adjusted to accommodate
micro-controllers using 3.3 V.
1. DA-15 Interface
2. Two Digital I/O ports
3. NTC input
4. Two Analog Output Ports
5. Real Analog Output
6. Autonomous Operation to Analog Output
7. Optional Use of 5 V - 36 V Power Supply
8. RS232 Operation
9. Adjustable Baud Rate via USB or Serial Communication (SCPI commands); The default BAUD
Rate is 115200 Bit/s.
10. UART Operation (i.e. for Control via an External Micro-Controller)
11. Instrument Control using SCPI commands (Serial Communication)
12. Power Meter Control and Output via USB
